Feature Request: Mouse-drag on numbers in UI and Eyedropper improvements.

Could Adobe please alter the UI so that all and any number boxes are made so that we can lower or raise the number via dragging on it with the mouse? For example, I think all of the numbers in the UI in After Effects work in this way. Perhaps holding shift whilst doing this would snap them to useful increments, too.

Eyedropper improvements: This seems like an obvious thing to have in the UI (I think Photoshop behaves in this way), but when we double click on a colour/stroke pot to bring the Color Picker box, we don't seem to be able to use a colour picker outside of this box to grab colours from inside the UI/document or from elsewhere on our screen from different apps. Could you please make this work how it does in Photoshop?

Also, it is quite handy when using the Eyedropper that it'll copy the stroke/fill style of whatever you want to sample, but is there a way where if we've got (for example) the fill set to a correct colour, but then we want to only change the stroke colour, that the eyedropper doesn't change both colour pots?
